Flavouring sports nutrition is a technical problem
Whey, plant proteins, creatine, BCAAs, caffeine and vitamin blends all bring bitterness, astringency or off-notes that ordinary food flavourings can't hide. Effective sports nutrition flavouring has to do two jobs at once: mask the base, then deliver a profile consumers actually enjoy at high protein loads and low sugar levels.
As a UK supplement flavour manufacturer, EC Aroma develops flavour systems specifically for these matrices — balancing masking, sweetness perception and stability across powder, RTD and bar formats. Protein powder flavouring is the core of the work: getting chocolate to taste like chocolate at 80% protein, not like whey with an aftertaste.
Applications we flavour
Protein powders
Whey, casein and plant-protein blends — chocolate, vanilla and salted caramel staples through to bakery and dessert profiles like cookies & cream and banoffee.
RTD & hydration
Water-soluble flavour concentrates for clear protein waters, electrolyte drinks and energy RTDs — clean solubility with no ring or haze.
Pre-workout & aminos
High-impact fruit profiles (blue raspberry, cherry, tropical) engineered to mask bitter actives such as caffeine and beta-alanine.
Bars & snacks
Heat-stable flavourings for protein bars, balls and baked formats.
Profiles that sell in 2026
Alongside the anchors — chocolate, vanilla, strawberry — we develop the trending profiles UK supplement brands are launching now: salted caramel, blue raspberry, cherry cola, tropical punch, matcha, and nostalgic sweet-shop profiles. If you have a benchmark in mind, our bespoke flavour development service can match or reinvent it exclusively for your brand.
Formats and solubility
- Water-soluble concentrates for powders, clear RTDs and hydration products.
- Oil-soluble and heat-stable systems for bars and baked applications.
- High-strength concentrates — dosage rates are application-specific; we recommend a rate for your matrix and keep cost-in-use low.
Compliance
All flavourings are food grade and compliant with UK/EU flavouring regulation (EC 1334/2008) and CLP, with documentation, allergen statements and specifications supplied on demand to support your own supplier questionnaires and quality audits.

Sports nutrition flavouring questions
Can your flavourings mask the bitterness of plant proteins and actives?
Yes — masking is central to how we build sports nutrition flavours. Profiles are formulated to cover the bitterness and off-notes of pea, soy and other plant proteins, and of actives such as caffeine, creatine and beta-alanine, then application-tested in real bases rather than just water.
What dosage of flavouring is typical in a protein powder?
There is no single figure — it depends on the application, the profile and the protein load and composition of your blend. Tell us your base and target intensity and we’ll recommend a starting rate, then confirm it by bench trial in your own product; samples are available from 1 kg for exactly this purpose.
Can I trial a sports nutrition flavour in my own base before committing?
Yes. Samples typically ship within days, and our 1 kg MOQ means you can run pilot batches in your own protein or electrolyte base before scaling to production volumes.
